Papillary thyroid cancer subtypes

Case Study: Treating Papillary Thyroid Cancer

Reprezinta cresterea de volum a glandei tiroide, prin prezenta unor noduli, unici sau multipli, pastrand un nivel normal de hormoni tiroidieni. Este un termen enspecific care defineste cresterea tiroidei in talie si in greutate de cause diverse, la persoanele papillary thyroid cancer subtypes, hipotiroidiene sau hipertiroidiene.

Etiopatogenie: 1. Defectul genetic de sinteza de hormone tiroidieni, apare in gusa congenitala- hormonii tiroidieni fiind insuficienti, hipofiza stimuleaza sinteza de hormone tropi, cee ace implica proliferarea epiteliului follicular tiroidian cu hiperplazia secundara a acestuia. Papillary thyroid cancer subtypes varza si conopida si unele medicamenete, interfera cu productia de hormone tiroidieni si aparitia gusei.

Gusa nodulara non toxica: este o crestere a tiroidei pe seama unei papillary thyroid cancer subtypes continute sau repretitive in raspunsul deficient de hormone secretati de glanda tiroida. Clinic: Se observa masa cervicala ce comprima structurile din jur papillary thyroid cancer subtypes determina simptome ca dispnee si disfagie; uneori poate fi prezent un nodul tiroidian hiperfunctional toxicsi se numeste sd.

Macroscopic: - gusa difuza: glanda marita uniform de volum mai mult de 40gsimetric, cu aspect cenusiu, translucid, papillary thyroid cancer subtypes din cauza prezentei coloidului; - gusa nodulara — marire de volum asimetrica, cu aspect multinodular pe sectiune; nodulii au aspect brun-galbui sau brun-roscat, gelatinos, in functie de cantitatea de coloid; nodulii sunt incapsulati; frecvent se observa zone hemoragice, chistice de scleroza si de calcificare.

Microscopic: Gusa difuza prezinta hiperplazie si hipertrofie difuza a epiteliului folicular, ocazional formand structuri papilare; pe masura ce afectiunea se cronicizeaza, cu episoade de stimulare si involutie administrare de iodaspectul coloid si nodular devind evident, cu foliculi dilatati chistic si epiteliu aplatizat sau cuboidal, nodulii au dimensiuni variabile si sunt separati prin septuri fibroase; frecvent se identifica zone de calcificare, scleroza, hemoragie si depozite de hemosiderina.

Two morphologic forms of goitre are distinguished: A.

A celularitate abundentă într-o metastază de tumoare neuroendocrină în tiroidă. B celule cu nucleu mărit de volum și citoplasmă foarte puţină. Cromatină nucleară cu aspect granular. C, D celule izolate, foarte discret pleomorfe, cu nuclei măriți de volum și cu aspect de tip endocrinoid al cromatinei nucleare.

Diffuse goitre simple nontoxic goitre or colloid goitre. Nodular goitre multinodular goitre or adenomatous goitre.

Pathogenesis of Goitre The pathogenetic mechanisms of both forms of goitre can be considered together since nodular goitre is generally regarded as the end-stage of long-standing simple goitre Fig. The fundamental defect is deficient production of thyroid hormones due to various etiologic cancer maladie hodgkin described below, but most common is dietary lack of iodine. Deficient thyroid hormone production causes excessive TSH sarcoma cancer rare which leads to hyperplasia of follicular epithelium as well as formation of new thyroid follicles.

Cyclical hyperplastic stage followed by involution stage completes the picture of simple goitre.

Repeated and prolonged changes of hyperplasia result in continued growth of thyroid tissue while involuted areas undergo fibrosis, thus completing the picture of nodular goitre. Diffuse Goitre Simple Non-toxic Goitre, Colloid Goitre Diffuse, nontoxic simple or colloid goitre is the name given to diffuse enlargement of the thyroid gland, unaccompanied by hyperthyroidism.

Most cases are in a state of euthyroid though they may have passed through preceding stage of hypothyroidism due to inadequate supply of iodine. TSH levels are invariably elevated.

In general, goitre is more papillary thyroid cancer subtypes in females. Simple goitre often appears at puberty or in adolescence, following which it may either regress or may progress to nodular goitre.

Epidemiologically, goitre occurs in 2 forms: endemic, and non-endemic or sporadic. Endemic goitre. Such endemic areas are several high mountainous regions far from the sea where iodine content of drinking water and food is low such as in the regions of the Himalayas, the Alps and the Ande.

Of late, however, the prevalence in these areas has declined due to prophylactic use of iodised salt. Though most endemic goitres are caused by dietary lack of iodine, some cases occur due to goitrogens and genetic factors.

Goitrogens are substances which interfere with the synthesis of thyroid hormones. These substances are drugs used in the treatment of hyperthyroidism and certain items of food such as cabbage, cauliflower, turnips and cassava roots.

Sporadic non- endemic goitre. Non-endemic or sporadic simple goitre is less common than the endemic variety.
